I'm certainly not an expert! The cueva label says "May cause russeting
of susceptible apple varieties. Do not exceed the 1.0 gallon of product/
100 gallons water use rate." When Kerik started me on this program, he
said "we never get fruit finish injury. However, depending on your spray
volume, you could have a different experience. We use 100 gal/A in our
block."

I hope you meant a Low volume of water. High volume = slow drying =
russeting. This is very easy to demonstrate. We do it as a "control"
in plots. We always have copper induced russeting at 500 L/ha and none
at 225 L/ha.

Kerik Cox at Cornell has done trials with this combination for cedar
apple rust, summer fungal diseases, and fireblight and has had good
results.
We started using the combination in our organic orchard last year and
did not see any problems with fruit russeting. Kerik did caution me
to use a high volume of water to avoid toxicity from the copper (100
gallons per acre vs our normal 50 in our high density orchard). We
have used 2 qts/acre Cueva + 2 lbs/acre 2ble nickel.
Kerik also suggested that the 2ble nickel might be unnecessary and
that cueva alone might be sufficient, but that may be theoretical at
this point. The 2ble nickel does add a lot of cost.

A couple years ago I recall discussion regarding the use of
Cueva/Double Nickel combination as an alternative and/or rotation
with strep for fireblight management. Is anyone aware of further
research regarding this combination esp as to regards to crop safety
and efficacy ?
